The number of coat to be applied on the roof depends on the type of coating you have. For example, acrylic and urethan coats should be applied at least twice while silicone coat can be applied once. Purchase a quality coat suitable for your RV.
Sometimes you may not need to actually remove the whole roof because you have a small opening that can easily be fixed with a sealant.
Find an RV sealant to seal the cracks and any possible places that allow leaks such as around vents, the a/c unit, roof edge, or window gaps.
The type of sealant to use depends with the magnitude of damages to be sealed. Sealant can come as a tape such as EternaBond, liquid, or a caulk. Clean the area to be sealed before applying the sealant.
A cleaned surface enhances the adhesiveness of the sealant to the roof such that it sticks well and completely seal the gap. Keep in mind that some roof coats act as sealant. Do your homework to be sure and save some cost.

How Often Should You Reseal Your RV Roof?
You should reseal your roof at least once a year as part of general maintenance of the RV. Although some RV have been resealed even after 3 years since some people only reseal once they have a damage such as leaks.
However, some people may have to reseal more than once depending with the actual condition of an RV. I mean an accident such as a treefall on the roof would require resealing even when you have not scheduled to do so.
Damages from water significantly reduces the value of your trailer and if you want to resale then you can easily go for a loss for massive repairs that could be prevented by regular sealing maintenance.
Leaks can occur and you can easily trace where the leak is coming from. However, when conducting a general sealing maintenance be sure to inspect and if possible, seal the roof sides, front, and even the rear cap attachment seams.
To be more specific, anything that sticks out of the roof can have a leak and should be resealed.
If you can seal the roof by yourself it is ok, and if severe damages are present have the dealer sort you. Also, if the RV is still under the warranty simply get the dealer fix the leaks at no cost.
Also, it is cheaper to do regular reseal than wait for massive damages to happen for you to conduct a reseal which may be costly especially is you will require an actual change in roof top.

Flex seal spray is a liquid that is applied as a spray. It is easy to apply since you do not require rollers or brushes. Although extra caution should be maintained since it can damage your eyes. Wear eye googles and other protective gear.

How Long Does an RV Roof Last?
Ideally, an RV roof should last at least 15years to 20yrs and even more after which a complete roof replacement is needed. However, most roof do not reach their lifespans for several reasons such as poor maintenance that allows damages such as leaks, and accidents such as tree fall among other issues.
Often, leaks are likely to occur after 10 years. Although in some extreme weather conditions leaks can occur as early as 5 years due to corrosion by nature. You also need to be keen whenever you purchase a used RV since leaks could be a problem.
Leaks that can cause sever roof damages should be prevented through maintenance. A good coating and sealant use on the roof saves you the extra cost of replacing the whole roof.
Also, not that if you allow leaks to go on for long the value of your RV depreciates too fast and resale can bring much losses.
How Long Does a Rubber Roof Last on an RV?
With proper maintenance, rubber roof can last at least 12 to 20 years. However, poor maintenance can reduce its durability to a maximum of 8 years. So, be sure to maintain your roof well.
Maintenance Do’s and Don’ts
For proper maintenance, the following are Do’s and Don’ts:
- Clean with soap and water. Do not use petroleum distillates since it can cause the rubber to swell or be loose.
- Scrab with moderation to remove dirt debris. Overscrabbing wears off the roof
- Do not use harmful chemicals such as toilet detergents since they can cause corrosion
- Apply suitable coatings and sealants for rubber roofs.
- Do not store under sunlight. Cover when not in use. Sunlight degrades the rubber roof and reduces the durability of the roof
How Long Do Roof Coatings Last?
Generally, most coating can last up to 10 years or more. However, the durability of the coat is dependent on several factors including manufactures specification, weather conditions, and roof maintenance.
Often, extreme weather conditions is likely to reduce the overall lifespan of coat and you may be required to coat before it actually attain its estimated lifespan.
Furthermore, accidents and tree falls can cause scratch or peeling of the coat and you may be required to replace. In addition, lack of proper maintenance is a threat to coats durability.
For instance, cleaning the roof without following simple guidelines such as washing with pressure wash, using too much pressure and hard bristle brush, using corrosive distillates such as some petroleum products can actually destroy the coat.
How Do I Waterproof My Roof?
Water leaks through the roof is not only a nuisance to comfort but also destroys the roof and may result in costly repairs. So, sealing leaks is important. Furthermore, making the roof water proof could be a good idea.
Follow these guide to water proof your roof:
step 1
Remove all debris such as leaves, branches, and accumulated dust from the roof. You may need a soft brush to do this work
step 2
Use soapy water and pour on the roof. Leave it for some minutes to allow softening of dirt and debris that stuck on the roof.
step 3
Use a long and soft bristle brush to clean the roof.
step 4
Rinse with clean water and let it dry.
step 5
Around any projections, dents, and junctions to the roof, cover or apply a sealant it may be a liquid, or a tape. Allow time to dry or cure
step 6
Coat your RV with a good coat that is waterproof or water repellant. Some have sealants mixed. Coat every corner of the roof including around any projections from the roof.
step 7
Leave to cure. Your roof is water proof.
How Do I Stop My Roof from Leaking Inside?

Also, you can learn more on better maintenance of your RV holding tanks.
Can I Pressure Wash My RV Roof?
No. It is not recommended. It is not a good idea at all because you will cause more damages than good. In fact, pressure wash can make u spend more on maintenance and even repairs that could be avoided.
Pressure was can wear off RV seals, remove paint, and destroys caulking. In worst case scenarios, removal of coating and sealant can cause roof leaks and you won’t enjoy the ride.
You may even be forced to halt your trip during harsh weather to fix the damage that could have otherwise been prevented.
I know a pressure wash is fast and even much easier than washing manually with your hands to remove dirt, debris and bird dropping. However, think about the damages you will incur and the cost of repairs.
Just do manual wash with your hands, use soap and water. Low to mild brush can be used to clean rubber and fiberglass roofs. Also, for all roofs do not apply too much pressure to scrape off dirt.
To make your work easier, consider pouring the soapy water over the roof to make it wet and leave for about 10 minutes before starting to clean to soften all dirt. Scrub gently using brush or a piece of cloth or towel, with soapy water. Rinse with clean water and allow it to dry.
Practice caution. Ensure the brush has a long handle or the towel is tied to a stick to make it long enough since the roof would be slippery. Especially if the RV roof is curved.
Soapy water makes the roof slippery and being on top of the roof while directly cleaning with a towel using your hand poses a risk of you falling to the ground.
